Question: How do you prevent the unit from being stolen?
Answer: We have three safety features that prohibit theft of the units: 1) The tongue is able to be taken out of trailer once setup into place, 2) The tongue can be left in and a padlock can be placed into the hitch receiver, or 3) You can get the optional wheel locks that keep unit from being transported.

 

Question: How hard are they to program?
Answer: Our Portable Message Signs are very easy to program. Please see our instructions for programming under “support documents” for each model.

 

Question: How long will they run?
Answer: This depends on how the systems will be run & how much sun they will receive each day. Our Systems should run year round 24/7 in most cases and the battery bank should let the unit run for about 21-30 days without solar.

 

Question: What can you display on the message signs?
Answer: You will be able to display any text you would like to put on them and also put graphics and arrow symbols on our full matrix models. They come with at least 215 preprogrammed messages when you receive your unit.

 

Question: How many characters will fit on them?
Answer: Our standard system will display three lines of eight characters per line. Our full matrix message signs will display three lines of optional 10-12 characters per line, if needed.

 

Question: How many batteries do you use?
Answer: Please see specifications on each model under “support documents” on the website.

 

Question: How much sun do I need to run this?
Answer: Our standard system should be just fine in most cases. When you get into your more northern states then you may require additional solar and batteries, but it also depends on how long the system will be run.

 

Question: What size message board do I need in my state?
Answer: Every state is different on their needs but we basically have two models to choose from for state roadways. The full matrix (can display text and graphics) and the character matrix (displays text only). You will have to check with your State Department to find exactly which type you will need. All models will work perfectly for any county or city streets.

 

Question: What options are available for these?
Answer: There are tons of options for these message signs, but some of the most popular are: radar, cell modem, GPS, Central Software Management, and much more. Just go to our “options” tab for each model to see available options.

 

Question: Do you rent these or just sell them?
Answer: K&K currently just manufacturers them to sell. If we have older, refurbished units on hand, we will rent to our local market.

 

Question: How many messages will they hold?
Answer: Our systems come with 215-260 preprogrammed messages and 100 user changeable slots that you can place multiple messages in.

Question: If the batteries run down, how long will it take to recharge them?
Answer: If hooked up to the internal AC charger, this charging process should not take over 24 hours.

 

Question: What is the quick selection switch?
Answer: K&K Systems’ quick message selection switch allows users to create their 16 most used messages. Selecting the correct message is easy; just turn the thumb wheel to desired number.

 

Question: Why do I need the solar to tilt and rotate?
Answer: The solar tilt and rotate is designed to allow user to gain as much energy as possible from the sun. This works well in those winter months where there is not a lot of sunlight. (not available for all models)

 

Question: Do they meet all highway regulations?
Answer: Yes, our changeable message signs meet highway regulations.

 

Question: Do you carry parts for these?
Answer: Yes, we are the manufacturer and have spare parts available.

 

Question: Is there a way I can recharge the batteries myself if I need to?
Answer: Yes, our systems come with an AC battery charger that has an external plug for you to plug your extension cord into. The plug is located on the side of the control cabinet in newer models.

 

Question: Why do I need it to show graphics?
Answer: Graphics come in handy when trying to display a message as simple as possible followed by text. An example of this is a graphic of an “arrow left” followed by text message “merge left”.

 

Question: How high will the display rise up and why do I need it to rise?
Answer: The display will rise to 7 feet to bottom of display. The display needs to be raised so drivers can see behind the unit in case there are pedestrians on the other side and to meet MUTCD guidelines.

Question: How do I raise it up and down?
Answer: There is a toggle switch located inside the control cabinet to raise and lower the changeable message display. You must also release the break located on the center mast pole before raising display.

 

Question: Do the messages flash?
Answer: They can be programmed to flash.
